Commands unique to I mode:
ESC 0
sets line spacing to 1/8 inch.
ESC 1
sets line spacing to 7/72 inch.
ESC 2
sets line spacing stored by a prior ESC A n.
ESC 3 n
sets line spacing to n/216 inch where n is a single binary coded byte.
ESC 5 n
sets auto LF if n=1 and resets it if n=0. A line feed is automatically performed when
a CR is received if auto LF is set.
ESC A n
stores lines spacing of n/72 inch with n being a single binary coded byte but the
stored line spacing will not begin until it is set by an ESC 2.
VT
moves to the next vertical tab stop or does a LF if no tabs are set.
ESC B
nnnnn0 sets up to 64 vertical tabs at each line n with each n being a single binary
coded byte and terminating with a 0 byte. ESC B 0 clears all vertical tabs.
ESC R
clears all vertical tabs and sets horizontal tabs to default values of column 9 and
every eighth column to the right.
If any document movement command (BS, LF, VT, FF, ESC n, ESC 4, ESC J n or ESC ])
has been preceded by any printable ASCII characters, they will be
printed before the
movement command is executed.
3.10.3 Print Commands
Commands common to both C and I modes:
CR
prints all preceding printable ASCII characters. There is no document feed due to
the CR unless auto LF has been set by a ESC 5 01 command and then a LF will be
performed.
SO
starts double width print. All characters received after an SO and before a SI, CR,
DC4, CAN, ESC W or feed command will be printed double width.
ESC STX Starts landscape (sideways) print for documents inserted rotated 90
clockwise.
Documents must be fed to the first printable column and 10 or 12 cpi selected
before ESC STX is issued. Following the STX is a single byte specifying the
document height in tenths of an inch. Printing will begin 0.25 inch below that
document height unless optional LF or ESC J feeds follow the document height
byte. Following the optional feeds are rows of printable characters each terminated
by a LF or ESC J. The last printable row must be terminated by an ETX (03 hex).
No commands other than LF or ESC J are allowed prior to the ETX. No more than
24 lines, each of no more than126 characters, may be printed.
ESC E
starts bold, double strike print in 10 or 12 character/inch.
ESC F
stops bold print.
ESC G
starts correspondence quality print.
ESC H
stops correspondence quality print.
ESC I n
starts correspondence quality print if n=2, normal print if n=0 and draft if n=5. Draft
should not be used on passbooks. DP8 draft print quality may be degraded in the
rightmost column (column 56 @ 10 cpi or column 67 @ 12 cpi).
ESC S 1
starts half-high subscript print
ESC T
stops subscript print
ESC W n starts double width print if n=1 and stops it if n=0.
